我在unity的第一个c游戏需要一些帮助(介绍playerprefs)

unity3d c#

xnx · 技术社区 · 6 年前

当我添加关于addMoney变量的player pref时,它默认profitCount为0,而实际上它应该是1。这是我的第一场比赛,所以这很容易被我误解或忽视。

public class moneyCount : MonoBehaviour
{

    float timeTillAdd = 1;

    public int addMoney = 1;

    public int money;

    public Text txt;

    // Start is called before the first frame update
    void Start()
    {
        money = PlayerPrefs.GetInt("Money");
        addMoney = PlayerPrefs.GetInt("addmoney");
    }

    // Update is called once per frame
    void Update()
    {
        PlayerPrefs.SetInt("addmoney", addMoney);


        if (Time.time >= timeTillAdd)
        {
            money += addMoney;
            timeTillAdd++;

        }


        txt.text = money.ToString();

        PlayerPrefs.SetInt("Money", money);



    }


}

public class profitCount : MonoBehaviour

    public int profitAmount;

    public GameObject moneyManagerObj;
    moneyCount mc;

    public Text txt;

    // Start is called before the first frame update
    void Start()


    {
        mc = moneyManagerObj.GetComponent<moneyCount>();
       // profitAmount = PlayerPrefs.GetInt("profitamount");
    }

    // Update is called once per frame
    void Update()
    {
        profitAmount = mc.addMoney;
        txt.text = profitAmount.ToString();

      //  PlayerPrefs.SetInt("profitamount", profitAmount);

    }
}

public class ShopManager : MonoBehaviour
{

    public int item1_cost = 50;
    public int item1_upgrade = 5;
    public int item1_tier = 1;
    public int item2_cost = 50;
    public int item2_upgrade = 5;
    public GameObject moneyManagerObj;
    moneyCount mc;

    public Text txt;
    public Text item1;
    public Text item1_text;

    // Start is called before the first frame update
    void Start()
    {


        mc = moneyManagerObj.GetComponent<moneyCount>();
        item1_cost = PlayerPrefs.GetInt("Item1_cost");
        //item1_upgrade = PlayerPrefs.GetInt("Item1_upgrade");
        item1_tier = PlayerPrefs.GetInt("Item1_tier");


    }

    // Update is called once per frame
    void Update()
    {
        item1.text = item1_tier.ToString();

        PlayerPrefs.SetInt("Item1_cost", item1_cost);
        //  PlayerPrefs.SetInt("Item1_upgrade", item1_upgrade);
        PlayerPrefs.SetInt("Item1_tier", item1_tier);

        if (item1_tier > 0)
        {



            item1_text.text = ("Upgrade");





        }


    }




    public void on_click()


    {


        {

            if (mc.money >= item1_cost)
            {




                mc.money -= item1_cost;
                mc.addMoney += item1_upgrade;
                item1_tier += 1;
                item1.text = item1_tier.ToString();
                item1_cost += 50 * item1_tier;


            }



        }
    }

不要使用 PlayerPrefs 存储保存数据。这不是故意的。这是为了救玩家例如音量、全屏模式或输入类型。使用的文件是 纯文本
如果不存在保存数据,则读取的值为零(至少从PlayerPrefs读取)。你需要对此作出解释,但目前你还没有。当您转移到另一种保存方法时,您将得到其他错误,如空指针或文件未找到。您必须确定是否存在保存 只有这样,

好的,所以您将默认值赋给 addMoney 即初始化期间 public int addMoney = 1;

但是在你开始的时候,你又给它分配了一个尚未保存的值 addMoney = PlayerPrefs.GetInt("addmoney");

PlayerPrefs.SetInt("addmoney",addmoney);
